QUESTION ABOUT FUEL PUMP AND INERTIA SW

My girlfriend has a 2000 hyundai accent. It will run fine for a couple weeks but then will not crank. Good plugs, battery, will turnover but wont start so good starter. Plug wires are new. My dad is a pretty good mechanic and suspects that it is the fuel pump. Pump doesnt turn on when the ingnition switch is in start position. Fuses are good for fuel pump. Does this sound like a starter? Also, does this specific model have an inertia switch, and if so, where is it? And, is there an access panel to get the fuel pump out without dropping the fuel tank?
